Perhaps you should try some spelling variations:
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
than daun » than bau, than daem, than data
can data » can tata, dan data, fan data
ying jin » yang jin, jing ji, yang jie
jin how » john how
how hai » how has, how ai, how hci

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (wang yang)) ka ((than daun) OR (can data)) ying jin how hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) OR (wang yang)) ka ((than daun) or (can data)) ying jin how hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) OR (wang yang)) ka ((than daun) or (can data)) ying jin how hai ;*.
